Deploying certified copper capillary lines and control units customized to operate across the extreme thermal variations of Santiago, Antofagasta, and the southern agricultural hubs.
As the economic anchor of South America’s Pacific coast, Chile presents a highly sophisticated industrial profile requiring advanced HVACR (Heating, Ventilation, Air Conditioning, and Refrigeration) technologies. With over 6,000 kilometers of diverse microclimates—ranging from the arid, high-altitude mining environments of the Atacama Desert to the critical agricultural, fruit export, and wine cold chains of the Central Valley—the operational environment demands unparalleled reliability in refrigeration components.
Copper Capillary Tubes represent the pulse of these refrigeration cycles. These small-diameter tubes operate as the primary expansion device, restricting refrigerant flow to create the precise pressure drops required for phase transition. In Chile, where the agricultural export sector requires rigorous cold-chain integrity from farm to port (Valparaíso and San Antonio), any capillary malfunction can compromise millions of dollars in perishable shipments. Thus, Chilean procurement officers look beyond basic compliance; they seek metallurgical consistency, rigorous dimensional tolerances, and high structural resilience.
Additionally, Chile’s national commitments under the Kigali Amendment to phase down hydrofluorocarbons (HFCs) have triggered a rapid shift toward natural refrigerants, such as R290 (Propane) and R744 (CO2). These systems require highly specific interior diameter tolerances and superior burst-pressure profiles, which only deoxidized high-phosphorus (DHP) copper tubes can consistently provide.
Ensures consistent cooling cycles for critical agricultural and marine export products leaving Valparaíso.
Engineered to handle high pressure levels in modern green systems, supporting R290, R134a, and R600a.
Designed for flawless operation under intense conditions, from high-altitude desert mines to coastal ports.
Inside Taojun's advanced manufacturing center: Automated tube drawing & MES-integrated quality checks.
For high-performance capillary tubes, metallurgical integrity is non-negotiable. Our products are extruded and drawn from premium C12200 Deoxidized High Phosphorus (DHP) copper (copper content ≥ 99.90%, phosphorus content ranging between 0.015% to 0.040%). This precise chemistry optimizes weldability, resistance to hydrogen embrittlement, and long-term grain structure stability under constant high-pressure cycling.
Key technical specifications of our capillary tubes include:
In the modern procurement landscape, cost efficiency must be balanced with absolute reliability and logistical speed. Operating from our manufacturing base in Xiangshan, Ningbo, China, Ningbo Taojun Refrigeration Equipment Co., Ltd.

Precision HVACR system installations in South America demand custom engineering profiles. Due to the high concentrations of airborne dust and particulate matter in Northern Chile's mining zones (such as Calama and Antofagasta), refrigeration equipment requires superior sealing. Capillary tubes must be paired with high-capacity copper filter driers to remove moisture and prevent acid formation inside the compressor loop. Below are the primary deployment scenarios:
In central agricultural regions, maintaining a stable cold chain from harvest to the port of San Antonio is essential. Our capillary assemblies guarantee precise pressure drop regulation, allowing cooling units to maintain uniform temperature controls with minimal electrical fluctuation.
Operating in environments over 3,000 meters above sea level shifts ambient air pressure profiles. We customize internal capillary tube bores (tolerances of ±0.02mm) to ensure steady volumetric flow rates, counteracting reduced air density and high thermal variations.
For residential high-rises and commercial retail sectors in Santiago, our C12200 copper alloy capillary coils provide high fatigue strength, resisting micro-fractures caused by compressor startup vibrations.
A refrigeration system's efficiency depends on balancing capillary flow resistance with compressor capacity. A minor reduction in tube inner diameter (ID) can restrict refrigerant flow, raising head pressures and increasing compressor wear. Conversely, a loose tolerance can lead to under-expansion, reducing evaporator cooling efficiency. By maintaining strict control over copper grain sizing during drawing processes and utilizing nitrogen purging before sealing, we prevent oxidation. This ensures smooth flow and consistent thermodynamics across all system layouts.
